3 Claims. (Cl. 24052.15)

This invention relates to a lighting fixture.

An object of the invention is to provide a lighting fixture having a light shade which is adjustably supported so that the same may be arranged for directing light rays in any desired angular relation and which may be readily released and readjusted without the necessity of unscrewing and tightening fastening means.

Another object of the invention is to provide a lighting fixture of said character in which the light shade is transportable and can be utilized in various types of brackets and supports so as to provide a drop light, or a wall light, and which may be arranged on a floor stand or on a floor bracket and the like.

Still another object of the invention is to provide a lighting fixture consisting of a metallic shell or shade of general globular formation together with a bracket having a magnet provided with an outer face of corresponding arcuate formation which is adapted to attract and hold the shell or shade in any desired angular relation.

With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiments of the invention are illustrated.

In the drawings:

Fig. 1 is a view in elevation of a light shade supported by a drop ceiling fixture shown partly in section and constructed in accordance with the invention.

Fig. 2 is a perspective view showing the under side of the magnet.

Fig. 3 is a similar view of the light shade supported on a stand embodying a modified form of the invention.

Fig. 4 is a perspective view of a light shade supported by means of a modified form of ceiling bracket.

Fig. 5 is a similar view of a light shade supported by a floor bracket embodying still another modified form of the invention.

Referring to the drawings, the lighting fixture is of the type for projecting light rays such as a spot light for display purposes and which may be used in show windows, show cases and the like for spot lighting articles on display therein and which may also be used for spot lighting walls or articles such as draperies, pictures and the like hung thereon.

In Figs. 1 and 2 of the drawings, the invention is illustrated in its application to a lighting fixture suspended from a ceiling 11 as a drop light and which includes a metallic shell or shade 12 of general spherical formation having an electric socket 13 adapted for receiving a bulb 14 therein and which is formed with a circular opening 15 located diametrically opposite from the socket 13 with the bulb 14 disposed substantially centrally within the shell for producing a conical shaped beam of light through the opening 15. The shell 12 is supported by means of a drop tube 17 connected at its upper end with a ceiling box 18 set in the ceiling 11 and removably secured thereto in any desired manner.

In order to removably connect the shell 12 with the drop tube 17, a magnet 20 is provided having oppositely disposed poles 21 and 22 arranged on opposite sides of a transversely extending slot 23 and which is secured to the drop tube 17 by means of a screw 24 having its upper end anchored in a cap 25 threadedly secured on the lower end thereof. The magnet 20 is formed with a lower face 26 of arcuate formation in cross-section corresponding substantially to the arcuate formation of the outer surface of the shell 12. The magnet is located substantially centrally within an ornamental canopy or shell 28 having 2,695,950 Patented Nov. 30, 1954 an annular rim 29 which is formed as a continuation of the arcuate formation of 'the lower face 26 of the magnet 20. This provides means by which the metallic shell 12 is releasably secured by the magnetic attraction of the magnet 20 against the arcuate face 26 thereof and against the annular rim 29 to firmly hold the shell thereagainst. Due to the spherical formation of the shell 12 the same may be released from the magnet 20 by a downward pull thereon and readjusted to any desired position thereon for directing the rays through the opening 15 in any angular relation about the vertical axis through the drop tube 17 or downwardly about said axis. The magnet 20 is formed with a rounded or beveled peripheral edge 31 so as to prevent the magnet marring the metallic shell 12 when the shell is drawn thereagainst and it is to be understood that the arrangement of the magnet within the canopy 28 provides an annular contact of the metallic shell 12 against the periphery of the canopy in spaced relation from the magnet which firmly holds the metallic shell thereagainst. An electric cord 32 extends through the metallic shell 12 and is connected with the socket 13 with the upper end of the cord extending upwardly through the drop tube 17 and connected with electrical conductors through the ceiling box 18.

The fixture may include a stand as illustrated in Fig. 3 of the drawings. In this form of the invention, the stand 40 is provided with a ring 41 at its upper end and located centrally within the ring is a magnet 42 similar to the magnet 20 in the previous form of the invention and which is secured to the stand by means of a screw 43. The upper face of the magnet 42 is of dished formation while the upper face of the ring 41 is similarly curved in cross-section for receiving the metallic shell or shade 44 thereon. The metallic shell 44 is similar in all respects to the metallic shell 12 in the previous form of the invention and is formed with a circular opening 45 similar to the opening 15 in the previous form of the invention which is located in oppositely disposed relation from the socket 46 therein. The socket 46 is adapted to be connected with a source of current supply through the electrical cord 47 and the metallic shell 44 may be disposed in any angular position upon the ring 41 and secured in position thereon by means of the attraction of the magnet 42.

Instead of the drop tube 17 or the stand 40 in the previous forms of the invention, the metallic shell may be magnetically secured in operative position as a ceiling fixture as illustrated in Fig. 4 of the drawings, or on a floor support as illustrated in Fig. 5 of the drawings. In Fig. 4 of the drawings, the metallic shell or shade 50 is adjustably secured in position adjacent the ceiling 51 by means of a magnet 52 secured by the screw 53 to the ceiling box 54. The magnet 52 is similar to the magnets 20 and 43 in the previous forms of the invention and the same is arranged substantially centrally of the ring or canopy 55 secured to the box 54. For supporting the metallic shell on the floor a support may be provided as illustrated in Fig. 5 of the drawings which is formed with an annular rim 61 and located within the support 60 is a magnet 62 secured thereto by a screw 63. The magnet 62 is provided with a dish-shaped upper face 64 similar to the formation of the magnets in the previous forms of the invention and the rim 61 is correspondingly shaped in cross-section so as to receive the metallic shell or shade 65 in position thereon and which may be adjusted thereon for projecting the light rays through the opening 55 in various angular relations with reference to the support 60. The support 60 isof weighted construction and is formed with a flat bottom face 67 for supporting the same on the floor 68 or other flat surface.
